'At present, the global understanding of the source of marine plastic waste and micro-plastics, transportation routes and their eco-environmental effects is insufficient, research methods are not unified and standardized, and research on marine micro-plastics is still in its infancy. ' July 8, at Professor Li Daoji, director of the Ocean Plastics Research Center of East China Normal University, at the 2018 Annual Meeting of the Marine Civilization of the Guiyang International Forum on Ecological Civilization.
'To date, China's marine microplastics research has covered various aspects of possible research areas, including microplastic abundance in various habitats, analytical methods, bioaccumulation, toxic effects, microbial degradation, and microplastic contamination control and Management, etc. ' Li Daoji said, however, the current global understanding of the sources, transport routes, fate and ecological effects of marine plastic waste and micro-plastics is still seriously inadequate. The research methods have not been unified and standardized so far, and this new The research efforts and measures of the threat of the marine environment are quite different in different regions of the world.
At present, the world's most concerned about marine micro-plastics is Europe, America, Japan, South Korea, China and other countries and regions, but in general, research is still in its infancy, although studies have shown that micro-plastics can enter humans through aquatic products, etc. However, its health risks have not been confirmed.
Li Daoji called for extensive international cooperation on a global scale. Specifically, it includes: Establishing a globally unified marine microplastics research monitoring, analysis and identification method to study and determine the flux of plastic waste and microplastics in global rivers and riparian systems; Conduct surveys, transport and life cycle studies of marine microplastics from rivers to estuaries, deep seas, polar regions, etc.; study on the toxicological effects of marine microplastics at different environmental concentrations, and evaluate microplastics for marine ecosystems and human health. Risk and impact.
